, wmm m HADDEN, or GRAFTON, rnnnsrnvnnra 1 TROLLEY-SUPPOBT,

- To all whom it may com/era:

' Be it known that I, WILLIAMI-IADDEN, a citizen of the United States,residing at Grafton, in the Q I ltYv of Allegheny and State; ofPennsylvania, have invented certain' new and useful Improvements inTrolley-Supports, of which the following is specification.

V This invention relates to improvements in trolley supports and.has/foritsyobject to provide a trolley support'soconstructed that thetrolley wheel may follow any curved or zig-zagged line of wire-withoutdanger of jumping from said wire. V

7 Withthe above and other objects in view I have invented thetrolleyharp illustrated in the accompanying drawings in which,

Figure 1 is a side elevation of myimproved device, Fig. 2 is anenlargedfragmentalsectionalview thereof, Rig. 3 is a "longitudinal central,sectional view taken on line A, and I Fig. 4 is a top plan view of'thedevice. 7

Like reference characters indicate like parts through the "specificationand in the several views in the; drawings in which 1 1s a support-mgmember hav ng a fiar ng 0r span shaped end 2 the end13+ of which formsa'track the purpose which will be later explained. Upon the rear end ofthe memher 1 is a ball 4 around which the'curved, ends 5 and 60f themember 7 form a socket.

7 To said member 7 which is formed of a' pair f thereof wherebysaidlmember 7 may have 10 of said member 7.7 A cut away portion,

of parallel bars 8 and. 9 integrally or fixedly! connected at theforward end 10 thereof is pivoted in its center a trolley wheel 11. A

-member 12 is secured tothe parts 8. and 9 of the member 7 and formslbearing for one end of the rollers13, l4: and 15,'the other ends ofwhich are journaled into the portion 10 of the member '7, the rollers 13and 14 resting on top of the track 3 and the I roller 15 abutting theunder surface lateral movement in relation to said member 1 which isfixed to a trolley pole 16 and a brace 17 connects said pole and the end18 is provided in said flared end 2 whereby said member 12 may projectthrough to the under side of the member 1 The free ends of the member 7are secured together by a bolt 20. Secured to the other end 10 is aspring a the free ends of which are adapted to engage the edge of thepart 3 to cause fi ientf iction to prevent too free a move 'ment of themembers 7. i v a Specification of Letters 'i ate nt Paten tdg'Application m asu ar am; ien seriaim. 614,414. 1 e r From the abovedescriptionit will beiread;

6. A trolley wheel support consisting of a pair of superimposed membersbowed outwardly from each other, a wheel mounted on the upper of saidmembers, said upper member being returned upon itself whereby the wheelis supported between said re turned parts, the free ends of said uppermember formed into a socket, the lower of said members having a ball onone of its extreme ends adapt-ed to operate in said socket, said lowermember having its other end formed fan shaped, the end thereof beingformed into an arcuate track to accommodate the loose end of said uppermember, said loose end having a roller thereon to engage said track, aspring on said loose Copies of this patent may be obtained for fivecents each, by addressing the Commissioner end adapted tofr-i'ctionallyengage the edge of said track anda trolley pole adapted to engage saidlower member centrally thereof.

7. A trolley wheel-support consisting of a pair of superimposed membersbowed outwardly from each other, one of said members being returned uponitself, a wheel mounted between said returned parts, said wheelsupporting member having its free ends formed into a socket, said othermember having aball adapted to seat in said socket.

8. A trolley wheel support consisting of a pair of superimposed membersbowed outwardly from each other, one of said members being returned uponitself, a wheel mounted between said returned parts, said other memberhaving a flaring end over which said first member is slidable, saidfirst member having a U-shaped end and a roller mounted therein toengage said flaring end.
